My present invention has to ydo with the connection of wire lines to bailers, sand the like; and it has for its cbpumps and y jec he provision'of a device. in the form of 5 a i, ire line attachment, for effecting connection between 'the line and abailer or any other device, the connection being of such character that by quit-lr manipulation of the coupling one bailer orthe like may be sepa- 10 rated vfrom the wire line and another bailer or any other device equipped with a bail may be expeditiously and easilyjattached to the line, and thisby one operative.

TWith 'the foregoing in mind, the invention in all of its details will be fully: understood claims when the same lare read in connection with the drawings, accompanying and form ing part of this specification, in which :.-5 Figure' l is an elevation showing my novel coupling as applied to a wire line; the construction being the best construction of which I am cognizant.

Figure 2 is a view atrightV angle-'s4 to Figure 1, and partly in elevation and partly in section.

Figure 3 is a cross section taken in the plane indicated by the line 3 3 of Figure 2.

Figure .4e is an elevation of the intermediatemember of the coupling, showing one of the longitudinal grooves in said member. Similar numerals of reference designate corresponding part-s in all of the views of the drawings.

l show at 1 in Figures 1 and 2 a wire line, and to said line is permanently connected the intermediate member 2 of my improvement. The said intermediate member 2 is provided with a reduced and exteriorly threaded upper portion 3, and at diametrically opposite vpoints in the member 2 are longitudinal grooves 4 which extend through the length of the member. As appears in Figure 2 the said grooves 4 are formed in the threaded part of the member 1 as well as in the unthreaded part thereof.

By comparison of Figures 2 and 3, it will be understood that the body 11 is provided with a. bore 5 of rectangular cross-section, and it will also be understood that the said bore 5 is tapered upwardly-i. e., the bore is larger at its lower end than at its upper end.

The wire line 1 is extended downwardly into the bore 5 of the member 11 and the said line 5S, ljlbbeted in the bore 5 or is otherwise from the following description and cured vto thev member 1 so as to, carry a considerableload without liabilityy of the membei' 1 being detached from-the wire line.

The ral'ibeting is designated in Figure 2 by 6. 60

In addition to the intermediate or body member 1,` the coupling comprises a loop member, designed to receive, in its bight any device having a bail, such for instance asa bailer, sandpump or the` like. The* loop member; Thas side'portions or arms 8 designed to enter andl rest in the grooves l -of the intermediate vor body member 2, and the upper portions,` of the saidarms 8 are rel duced, as designated by- 9, andare threaded, as designated byr 10, the threads being' designed when the' parts are relativelyl arranged as shown in Figure 2,I to coincide `with the thread on the upper reduced portion of the intermediate member or body 2.

The third orfcrownv member 4of my novel coupling is, designated by 11. It receives and is turnable about. and, movable rectilinearly on the line 1, and in, addition to the bore 12, is provided with a skirt 13,'interiorly thread-v ed at 14 to engage-,the threads 3 of the intermediate or body member 2, and the coin- 1cgident thread ron the arms 'of' the loopfmemer s.

In the practical use 'of my novel coupling it will be understood that when the crown member 11 is turned and moved upwardly out of engagement with the threaded portions of the loop member 7 and also, by preference, out of engagement with the threaded portionof the intermediate vor body member 2, the loopv member 7 may be readily removed from the body member 2 and the line 1. From this it follows that one operative is enabled to expeditiously and easily change the line 1 from one. bailer to another or to a sand pump or the like, the loop member 7 being adapted to be readily engaged with the bail'of a bail-er o r sand pump and being also adapted to be as readily moved rectilinearly into engagement with the body 2 and coupled by the crown member 11 to the line 1.

Notwithstanding the practical advantages of my novel coupling as set forth, the coupling is manifestly simple and inexpensive in construction and at the same time is compact vand therefore adapted to be used in spaces of small compass.

llVhile I have specifically describe-d the construction and relative arrangement of the parts embraced in the present and pie-A ferred embodiment of my invention of which I am aware, I do not desire to be understood as confining myself to the speciiic cons-truction and arrangement disclosed, my invention being defined by my appended claims Within the scope of Which changes in form and arrangement may be made Without departure from my invention.

Having described my invention, what I claim and desire to secure by Letters-Patent, 1S

l. A coupling comprising an intermediate member with a tapered bore of angular cross-section adapted to receive and be scoured to a Wire line or the like, sai-d intermediate member having exterior longitudinal grooves at diametrically opposite points and also having a reduced and exteriorly threaded end portion, a loop member havin side portions 'or arms vremovably arranged in saidgrooves and reduced at their ends and havings threads on the reduced portions adapted to coincide or register with the thread of the intermediate member, and a member having a bore for the passage ot a Wire line or the like and movable about and rectilinearly of said line and having an linteriorly threaded skirt portion for engagement with the threaded portions of the intermediate member and loop member.

2. A coupling comprising an intermediate member With a tapered bore of angular cross-section adapted to receive and be secured to a Wire line or the like, said intermediate member having exterior longitudinal grooves at diametrically opposite points and also having a reduced and exteriorly threaded end portion, a loop memberhaving side portions or arms removably arranged in said grooves and reduced at their ends and having threads on the reduced portions adapted to coincidev or register with the thread oit the intermediate member, and a member having a bore for the passage of a Wire line or the like and movable about and rectilinearly of said line and having an interior-ly threaded skirt portion for engagement With the threaded portions of the intermediate member and Vloop member, in

combination with the said Wire line extending loosely through the third-named member of the coupling and secured in the said taper bore of the intermediate member.

3. In a coupling, an intermediate member adapted to be attached toa Wire line or the like and exteriorly grooved and having an exteriorly grooved reduced endr portion, a loop member having side portions or arms removably arranged in the grooves of the intermediate member'v and also having the end portions of said arms reduced and threaded, the threads adapted to coincide with those of the intermediate member, and threaded means adaptedrto be moved on Vthe Wire line and det-achably connecting the arms of the loop member to the intermediate member.

In testimony whereof I aicix my signature.
